a) 20(x)=y
b) $120
Let x= number of hours
Let y= Cost of labor
20 will remain constant, what matters is how many hours are being worked. If it's $20 per hour then it's safe to assume 1 hour is 20 dollars worth of labor. Due to it being per hour you have to multiply the rate by however many hours worked to get your final cost.

Step-by-step explanation:
6 decimal places
0.005011 has six decimal places.
What is a decimal place?
'The place value of a decimal number is recognized according to the position of the dot or decimal point. The first digit to the right of the decimal point indicates the number of tenths and the second digit to the right indicates the number of hundreths.'
According to the given problem,
For the number 0.005011, after the decimal there are numbers up to the sixth place which is that there are six numbers.
For counting decimal places, we need to count the number of digits present to the right of decimal point.

Gina rented a truck for one day there was a base fee of 1275 there was an additional charge of 20 cents for each mile driven the total cost c in dollars for driving in miles is given by the following function
Answer:
[tex]1275+0.2m=c[/tex]
m is the amount of miles driven, c is the total cost.
Step-by-step explanation:
Since she has a flat fee of 1275, that's the 1275 in the equation and since we don't know how many miles she drives, that's the m in the equation for miles driven. Since each mile costs 0.20, that's the 0.2 in the equation. And since c is the total cost in dollars, that's the c in the equation.

8. The difference of thirty-one and seventeen
divided by the product of ten and four
Answer:
[tex]\frac{7}{20}[/tex]
Step-by-step explanation:
The difference 31 - 17 = 14
The product 10 × 4 = 40
Then
[tex]\frac{14}{40}[/tex] = [tex]\frac{7}{20}[/tex] ← in simplest form
The difference between thirty-one and seventeen divided by the product of ten and four will be 7 / 20.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The difference between thirty-one and seventeen will be expressed as,
⇒ 31 - 17
⇒ 14
The product of ten and four will be expressed as,
⇒ 10 x 4
⇒ 40
Then the difference between thirty-one and seventeen divided by the product of ten and four will be expressed as,
⇒ 14 / 40
⇒ 7 / 20
Thus, the difference between thirty-one and seventeen divided by the product of ten and four will be 7 / 20.

Amir stands on a balcony and throws a ball to his dog, who is at ground level.
The ball's height (in meters above the ground), xxx seconds after Amir threw it, is modeled by:
h(x)=-(x-2)^2+16h(x)=−(x−2)
2
+16h, left parenthesis, x, right parenthesis, equals, minus, left parenthesis, x, minus, 2, right parenthesis, squared, plus, 16
How many seconds after being thrown will the ball hit the ground?
Answer:
6 seconds
Step-by-step explanation:
h(x)=-(x-2)^2+16
We want h(x) to be 0 ( that is when the ball hits the ground)
0 = -(x-2)^2+16
Subtract 16 from each side
-16 = -(x-2)^2+16-16
-16 = -(x-2)^2
Divide by -1
16 = (x-2)^2
Take the square root of each side
sqrt(16) = sqrt((x-2)^2)
±4 = x-2
Add 2 to each side
2±4 = x-2+2
2±4 =x
2+4 = x 2-4 = x

the main floor of an auditorium ranges from 6 feet below the stage
to 8 feet above the stage. the floor of the balcony ranges from 26 to 37 feet above the stage. write the range of the floor levels relative to the stage in interval notation and in set-builder notation.
This is a simple problem of ranges, we will find that the ranges for the main floor and the balcony are:
[-6ft, 8ft] or {x ∈ R | -6ft ≤ x ≤ 8ft}
[26ft, 37ft] or {x ∈ R | 26ft ≤ x ≤ 37ft}
respectively.
We know that:
The main floor of the auditorium ranges from 6ft below the stage to 8 feet above the stage.
The floor of the balcony ranges from 26 to 37 feet above the stage
The ranges relative to the stage will be, in interval notation, the interval that contains the two extremes of the range.
For the main floor, it goes from -6ft to 8ft (the first one is negative because is 6ft below the stage) then this interval will be: [-6ft, 8ft]
While in set-builder notation we want to specify that the variable must be a real number, so we start with: {x ∈ R
And we need to specify that x can go from -6ft to 8ft, then we add the restriction:
{x ∈ R | -6ft ≤ x ≤ 8ft}
Notice that we use a close interval here.
While for the balcony, the minimum is 26ft and the maximum is 37ft, then the interval will be [26ft, 37ft]
For the set-builder notation we will have:
{x ∈ R | 26ft ≤ x ≤ 37ft}

Answer:
A
Step-by-step explanation:
This uses the sine law.
Sin(theta)/113 = sin(42)/120 Multiply both sides by 113
sin(theta) = 113*sin(42)/120
sin42 = 0.6691
sin(theta) = 113 * 0.6691 / 120
sin(theta) = 0.630008
theta = sin-1(0.63008)

Which One Does Not Belong? EXPLAIN your REASONING
Answer:
The last one
Step-by-step explanation:
0.3333..., 30%, 3/10 are parts.
The last one ( 3 circles) are 3 wholes.
(whole numbers)
I hope this helped:)...
:-)
Hey there! I'm happy to help!
30% is the same thing as 0.3, which is 30% of 1.
0.3 is what you multiply numbers if you want to see what 30% of that number is as 0.3 is 30% of 1, the whole number.
3/10 is the same value as 30% because 3 divided by 10 is equal to 0.3, which is 30%.
The dots in the boxes are also the same thing as 3/10. There are 10 boxes, and 3 out of the 10 have dots, which is 3/10 and 30%.
The one that does not belong is 0.333333...... This is equivalent to 1/3, which is greater than 30%, 0.3, and 3/10.

Which of the following set of points represents a function?
(4,3), (2, 1), (2, 9). (9, 4)
(3,5), (4,5), (5,9), (7.-2)
(-1,2). (-1, 4), (-1,8), (-1,9)
Answer:
Each of the domain values, x, should only output a single unique range value, y.
This example is a relation and not a function because the the domain value of -1 output 2 distinct range values.
-1 outputs a 3
and
-1 outputs a 5
If I were to draw a vertical line at the domain value of -1 that vertical line would intersect the points (-1,3) and (-1,5). Which indicates that the relation is not a function.

None of the following set of points represents a function .
